Abstract
A clutch cover assembly, in which a radially inner side spring force action point (an inside projection 44, for example) of a lever 40 is provided at a position radially outer than wire rings 34 supporting a diaphragm spring 30, a radially outer side spring force action point (an outside projection 46) of the lever 40 is provided at a position to cause a distance B between a rotation center 01 of the lever 40 and the outer side spring force action point to be shorter than a distance A between the rotation center 01 and the inner side spring force action point, and the lever 40 is adapted to multiply a spring force P of the diaphragm spring 30.
Claims4
A clutch cover assembly for a clutch having, in axial alignment, a pressure plate, a clutch cover covering said pressure plate and an approximately annular disc-like spring member disposed outside of said clutch cover for applying resilient clutch engaging pressure to said pressure plate;
- characterized by that said disc-like spring is a diaphragm spring supported, intermediate its inner periphery and its outer periphery, for pivotal, resilient, axial movement on spring fulcrums extending axially from said clutch cover, levers in radial alignment with each of said spring fulcrums, each of said levers having a radial inner end portion between said clutch cover and the outer periphery of said diaphragm spring and a radial outer portion pivotally mounted on said clutch cover about an axis normal to the axis of said clutch cover and said pressure plate, each of said levers having an inside projection at it inner end portion in contact with said diaphragm spring adjacent said outer periphery of said diaphragm spring and an outside projection, intermediate said pivotally mounted outer portion and said inner projection, in engagement with said pressure plate for transmitting the spring force applied by said diaphragm spring from said inner end portion of said lever through said outside projection to said pressure plate.
